Hello all. I found that a similar discussion was done almost 2 years ago. https://lists.freebsd.org/archives/freebsd-arm/2021-November/000600.html I'm using the official FreeBSD 13.2 release. uname -a FreeBSD macavity 13.2-RELEASE-p4 FreeBSD 13.2-RELEASE-p4 GENERIC arm64 freebsd-version -kru 13.2-RELEASE-p4 13.2-RELEASE-p4 13.2-RELEASE-p5 I created overlay dtb files for i2c and ds1307, and loaded them at boot. FreeBSD detected ds1360 as MAX77620 like below. Nov 12 16:17:18 localhost kernel: rtc1: <MAX77620 RTC> at addr 0xd0 on iicbus0 Nov 12 16:17:18 localhost kernel: rtc1: registered as a time-of-day clock, resolution 1.000000s My SBC just has Allwinner H5 and nothing like tegra210. I created a custom kernel to remove tegra210. The custom kernel is fine and can detect ds1307 correctly. Nov 13 06:21:52 localhost kernel: ds13070: <Dallas DS1307> at addr 0xd0 on iicbus0 Nov 13 06:21:52 localhost kernel: ds13070: registered as a time-of-day clock, resolution 1.000000s Is there any way to disable max77620 without creating a custom kernel?
